I've been thinking of another solution, include some more information in 
  .FILELIST eg:

# directory name
d usr
d usr/bin
# file name checksum
f usr/bin/foo md5sum
# link name target
l usr/bin/bar foo

This way we can get the md5sum from the file list rather than having to 
extract the file to get it's md5sum.
